Electric multipole moments, topological multipole moment pumping, and chiral hinge states in crystalline insulators

Electric multipole moment fluctuations in polar liquids.

A general expression for the distribution of the fluctuating 2(l)-pole moment M(l) of a spherical sample of dielectric material is derived on the basis of dielectric theory combined with statistical mechanics. The formulas are compared with results from computer simulations of a weakly coupled Stockmayer fluid and the agreement is shown to be excellent. Furthermore, we calculate the size of the...

Multipole Moments In

This paper contains discussion of the problem of motion of extended e.g. non point test bodies in multidimensional space. Extended bodies are described in terms of so called multipole moments. Using approximated form of equations of motion for extended bodies deviation from geodesic motion is derived. Results are applied to special form of space-time.

On the Electric Multipole Moments of Carbon Monoxide

Electric moments are relevant for many phenomena caused by intermolecular interactions [1-4]. Recent work [5-13] has provided evidence that models relying on the knowledge of the electric moments of the monomers can be used to predict molecular structures and properties of weakly bonded van der Waals systems. Not all electric moments are easily amenable to experiment [2]. Experimental determina...

Multipole Moments of Static Spacetimes

Multipole moments of axisymmetric spacetimes

In this thesis we study multipole moments of axisymmetric spacetimes. Using the recursive definition of the multipole moments of Geroch and Hansen we develop a method for computing all multipole moments of a stationary axisymmetric spacetime without the use of a recursion. This is a generalisation of a method developed by Herberthson for the static case. Using Herberthson’s method we also devel...
